Patented July 11, 1933 UNITED STATES PATENT OFFICE i i i 1 "WILLIAM JosnrI-r BYi-znE, or .InnrANaroLrs, INDIANA! i REVOLVABLE HULL wnsrrlne MACHINE Application filed May 13, 1931.. Serial No. 536,967.

This invention relates to the art of washing machines, particularly to a machme adapted to wash garments and the likein-a cleaning fluid such, for example, as naphtha as is commonly employed in dry cleaning establishments, and is a continuation in part of my application, for U. S. Letters Patent filed May 31, 1930, Serial Number 458,624, as relating to a safety blast relief cover.

One of the important objects ofthe inven tion is to provide a cover for arotatable tub or hull whichwill automatically open upon a predetermined amount of revolution of the An important object' of the invention is to provide arevolvable hull witha cover which upon accidental explosion of the yapors therewithin will automatically direct the blast of such discharge rearwardly away from the front side of the hull in order to avoid injury to an operator who may be? standing thereby.

A further important object of the invention isto provide a cover for arevolvable hull which may automatically lift by its rear portion upon an explosion within the hull and which has a forward portion normally engaged with the hull to prevent opening of such forward portion until after a predetermined degree of rotation of the hull.

A further important object of the invention is to provide means-for revolving an inner cylinder and the hull independently of each other. 7

A still further object of the invention resi-desin providing a hull with a one piece circumferential wall tohavean opening to receive therethrough a section of an inner c 'linderso that the cylinder may be installed and removed without necessity of having. to open up joints in the hullitself. 1

These and other objects such as the particular combination ofthe various elements which will be pointed out specifically in the claims below. will become apparent in the fol: lowing descr ption of the inyention as lllUS- trated in the which r Fi 1 is a fragmentary front elevation of a washing machine embodying my invention; Fig. 2, a fragmentary right hand end elevation; p

Fig. 9, a fragmentary left hand end'elevation of the modified form and of the cyl- Fig. 10, a left hand elevation of thehull I provide a supporting frame 15 'having the end standards 16 and 17 respectively. Each of the standards 16 and 17 carry rollers 18 and 19 spaced apartin the same horizontal plane to receive'thereon the wheels 20 and 21 concentrically carried on the ends of the cylindrical hull 22 whereby the hull is free to revolve on and is supported bythe rollers 18 and 19. The"wheels 20 and 21 are prefervent endwise displacement on the rollers, the

flanges 23'being on the outer sidesof the rollers toward the standards. I Thehull 22 is formed solely out of three ably provided with an outer flange 23 to prepieces, the two circular heads or ends and the one piececircumferential wall terminat ing' by the ends a and b, Fig. 5,.to leave an 9 opening entirely across the hull. I The hull is mounted to be free to revolve completely around by the wheels 20,and 21 rolling between therollers 18 and 19.. The purpose of p the h'ull22f-is to hold a quantity of washing fluid anda separate clothes container or cyl- 1 inder 2 is provided to be carried entirely within the hull by the trunnions 25 and 26.

Since the opening into the hull between edges a and '6 is less than the diameter of the cylinder 24 to be carried th'erewithin, I preform a cylinder 24 in two semi-cylindrical sections to have headsdividedon diametri cal lines whereby one section at a time may be inserted through the opening into the hull and then the other section to havethe two sections come together intothe finished cylmdrical body by having the respective heads slidingly come 1nto position by means of tongue and groove oints 28.

The two sections of the cylinder are then retained in the assembled position within the,

hull by means of a plate 27 concentrically posi- 'tioned on each head on the outer side thereof and there secured by bolts 28 through the two head sections. The trunnions and 26 extend perpendicularly from the plates 27 and axially of the cylinder to project through the central holes in the ends of the hull 22 and therebeyond into supporting bearings29 and 30 respectively carried on the standards 16 and 17. The hull 22 preferably carries packing glands about the trnnnions where they extend through the hull ends so as to prevent the washing fluid from splashing out around the hull in either direction and entirely in-.

dependently of the position of rotation of the hull 22. The cylinder 24 is of the usual. type employed in washing machines and has at least one door therein (not shown) which may i be brought around to coincide with the opening into the hull in order to permit access to within the cylinder. Since the cylinder may stop at any position upon stopping the pulleys 34, it is usually necessary to revolve the cylinder 24 around by handto bring its opening around to the hull opening.

In order to accomplish this additional movement of the cylinder independently of the power drive through the chain 32, I revolvably mount a shaft on the standard 17. On the end of the shaft 35which projects outward ly from the standard 17,1 mount asleeve 36 revolvably thereon and this sleeve has fixed thereto a sprocket 37 around which is wrapped a chain 38 which in turn is wrapped about a sprocket 33 on a second shaft 40, the shaft 40 being fixed in position against rotation and the sprocket 39 being rotatable therearound. The sleeve 36 is adapted to be moved longitudinally along the shaft 35 by means of a shifting lever 41 being pivotally mounted thereabove and having its lower end engaging within an annular groove around the collar. On the inner side of the sprocket 37 are 'a plurality of evenly spaced pegs 42 which are so spaced and shaped as to engage consecumay betweenthe'teeth ofthe sprocket wheel 31 when the sleeve 36 is in its inwardly shifted position.

Near the outer end of the shaft 35 is passed therethrough a pin 43 which may be received within similarly shaped slots 44 formed in the outer face of the sprocket 37. Upon rocking of the lever 41 to the dotted line position, Fig. 4, the collar 36 is shifted outwardly along the shaft 35 to carry the pegs 42 outwardly beyond the path of the teeth of the sprocket 31 and to carry the sprocket 37 against the pin 43 to have the pin received within the slot 44 whereby the sprocket 37 then being rotated around therewth. A hand wheel 45 is fixed to the sprocket 39 as a means of revolving the sprocket and correspondingly through the chain 38, the sprocket 37.

To prevent rotation of the hand wheel 45, a clutch member '46 slidably splined 011 the outer end of the shaft 40 is pushed inwardly to have the pegs 47 thereon engage or be received within holes in the face of the hand wheel, and since the shaft 40 is stationary the wheel 45 is then held against rotation. The shaft 35 has a toothed wheel 48 fixed to its inner end adjacent the end of the hull 22 to have its teeth engage between posts 49 accurately spaced around on the end of the hull 22., hen the collar 36 is shifted outwardly to carry the pegs 42 out of mesh with the sprocket 31 to have the sprocket 37 engage with the pin 43, rotation of the hand wheel 45 will then revolve the shaft35 to cause rotation of the hull 22 through the wheel 48' and posts 49.

The hull 22 is here shown as being provided'with a latch member 550 spring pulled against a plate 51 (see Figs. 1 and 5) at each end of which is a notch into which the latch may drop. The outer end of the latch is pivotally mounted on the stationary housing 52. r

A handle, 53 is provided as a means for rocking'the latch upwardly out of either of the notches in the plate 51 to permit the hull 22 to be revolved. The plate 51 is so mounted on' the end of the hull as to have the notches positioned whereby the latch will drop into the notch 0 when the hull has its door opening-in the upper or normal washing position and will have the notch d carried around to. permit the latch todrop there in when the hull opening is brought around downwardly to have the edge a lowered to permit unloading ofthe cylinder 24. Of course thehull may be revolved beyond either of these two positions upon holding the latch handle 53 outwardly to permit the plate 51 to pass therebeyond. A pair of arms 54 and 55 is mounted to have the respective arms pivotally supported at 100 '(see'Fig. on the frame 15 toward the upper ends, of the standards 16 and 17 and rockably carries therebetween at the outer ends of the arms a shaft 56 which extends entirely across and above the hull 22. A cover is provided to be carried over the opening into the hull and will carry the shaft 35 this cover is formed in two sections, namely, a rear section 57 which is rockably hinged by its forward end to the shaft 56 and a forward section 58 which is fixed rigidly to the shaft 56 by the straps 59 and 60. When the hull is in the normal upper position, the rear cover section 57 laps over the edge Z) at the rear and rests thereon by gravity. The front section 58 has an under-lip 61 which slips under the edge a while the forward section of the cover itself laps over on the outer side. Thus it is to be seen that while the section 57 may be raised and lowered in relation to the edge 6 of the hull, the front sec tion 58 cannot be raised or lowered by reason of the projecting 1113 61. i

New to permit access to within the hull 22, it is therefore necessary to revolve the hull 22 a distance suflicient to bring the edge it around downwardly from between the forward section 58 and the lip 61. During this travel cam blocks 62and 63 fixed on the ends of the hull 22 come under ends of the shaft 56 to raise it and lift both sections 57 and 58 of the cover at their ends supported by the shaft to provide a vent for the hull whereby should there be sufficient vapor within the hull to form an explosion upon the admittance of air, such explosion that might then occur takes place before the cover section 58 can swing open by reason of the lip 61 being engaged against the underside of the edge a. Such an explosion would then blow the rear section of the cover upwardly since its rear end is free and permit the blast of the explosion to exhaust itself rearwardly and away from the operator who may then be standing in front of the machine.

On the left hand side of the washing machine is provided a linkage system for raising the front cover section 58 upon continued rotation of the hull 22' in lowering the opening edge a. A link 64 has its upper end pivotally engaged to the arm 54 at a' point back of the shaft 56 andits lower end slotted and held along the bracket 65 by the pin 66 in such manner that by reason of the slot receiving thepin 66' therethrough, the shaft 56 may be raised only to the limit controlled by the length of the slot; This length is made to equal substantially the lift of the shaft 56 as produced by the cam blocks 62 and 63.. The bracket 65 is fixed on the standard 16 back of the bearing 29. Fixed to the outer end of the shaft 56 is a lever 65 in such manner that upon forward rocking ofthe lever 65 by its lower end, the cover section 58 will be rocked open when the lip 61 is free from the edge a.

Another lever 66 hasit-s upper end rockably attached to the inner side of the standard 16 at the upper end of the standard at 101 and to its lower end which terminates below the level of arm 65 is pivotally secured a connecting link 67 the other end of which has a slotted connection with the lower end of the arm 65." The bar'66 is preferably bent, near its middle toward the cam block 62 and between the pivot points .of the lever 66 and the lever 67 at the bend is a bar 68 pivotally secured thereto by one end and by its other end to the end of the hull 22, or as here shown as being pivotally attached to the cam block 62 which is attached to the hull. Aspring 69 is secured under tension between the lower end of the lever 66 and a downwardly projecting finger near the forward end of the bar 68.

Now as the hull 22 may be revolved clockwise, Fig. 3, as the cam blocks 62' and 63 have come under the shaft 56 to raise it and the edge a hasbeen withdrawn from over the lip 61, the bar 68 having. traveled with the hull 22 pulls the lever 66 forwardly to carry the link 67 forwardly also to the limit of the slot in the-forward end after which, continued travel of the link 67 rocks the arm 65 to inturn rock the upper endforwardly of the cover section58. Thus it is to be seen that an automatic front cover section open- 1? ing mechanism is provided.

Means for introducing the Washing fluid are provided. A supply pipe 70 is fixed to the frame 15 between the upper ends of the standards 16 and 17 and through a flexible" hose connection 71 is connected to a Y 72 the-outer'ends of which discharge into the transverse pipe 73 which'is supportedbetween the arms 54 and 55 to be raised and lowered therewithin. of the pipe'73' are extended a plurality of discharge nipples 74 which project through the rear cover section 57 in such a manner that the section may be raised and loweredabout the nipples.

In order to provide a positive stop against which the front'cover section 58 may rest when in the'open position,I provide a bar 75 carried above andfbetween the arms 54 and 55 against which the cover section may drop when opened up.

When thelfront cover section 58 has been opened upon rotation of the hull 22 asabove described, the hull 22 is held ina fixed position by means of the latch 50 dropping into teeth of th sprocket 31 and the hand wheel 45 is then revolved to bring the cylinder 24 around to the desired position under the opening through the hull 22. When the machine is to be used again, the lever. 41 is pushed rearwardly to the dotted line position, Fig. 4, to shift'the sprocket wheel 37 out away from the sprocket wheel 31 where-' From the underside upon the hull 22is then revolved in the reverse direction by means of the hand wheel to bring the plate 51 around to permit the latch to drop into the notch c and to then have the cover 58 lowered through the operation of the linkage above described and to have the lip 61 again brought under the edge a of the hull opening. The clutch member 46 is then pushed inwardly to prevent further movement of the hull 22 in addition to the latch 50 and the cylinder 24 is then ready to be revolved again upon rotation of the pulleys 34.

\Vher'e a cheaper type of washing machine is desired, the modified form as shown in Figs. 8, 9 and 10, may be employed. In this 'modified form the hull 22 is revolvably mounted between bearings and 81 on the standards 82 and 83 respectively but the hull 22 is held in fixed position by means of the straps84 and 85 being passed around the hull and pulled tightly thereagainst by the bolts 86 and 87 carried by the frame 88 of which the standards 82 and 83 are a part.

A cylinder 89 of the usual and well known type of construction is revolvably carried within the hull 22 and is driven independently of the hull. The hull 22 in this modified form is provided with a door opening toward its upper side as defined between the edges 02 and 11 of the circumferential wall thereof. 1 form. an arcuate door 90 to fit over this opening into the hull circumferentially therearound and provide the lower or front end of the door 90 with an under lip 91 which is adapted to pass under and inside of the edge g of the hull wall.

On the ends of the hull 22 on the upper sides thereof are mounted the vertically projecting hinge plates 92 and 93 respectively. These plates are each provided with similarly disposed irregular slots 94 into which project pins 95 and 96 from the ends of a bar 97 to which the rear end of the door 90 is fixed.

Referring now to the shape of the slots 94, each slot is provided with a central horizontally disposed portion 6 from the rear end of which is downwardly cut a notch From the forward end of the horizontal portion 0 of the slots is adiagonally upwardly extending slotted portion 9. The door 90 is provided with a lifting handle 98 and when the door is pushed to the closed position as indicated in Figs. 8 and 9, the lip 91 is on the back or inner side of the hull wall at the edge y and the pins 95 and 96 are still in the horizontal portions 6 of the slots 94 but at the forward endsthereof at the bottoms of the upwardly inclined portions 9.

Should an explosion take place within the hull 22 with the door in the position as above described, the front portion of the door cannot swing open by reason of the lip 91 being behind the hull wall edge, but the rear portion of the door may lift under the force of the explosion and allowthe pins 95 and 96 to travel upwardly along the slot portions 9 and thereby allow the blast of the explosion to strike the under side of the door and be deflected around rearwardly from the front side of the hull. When the force of the explosion has spent itself, the door will drop down by the pull of gravity and allow .the pins 95 and 96 to return to the horizontal slot portions 0;

lVhen the door 90 is to be openedtopermit access to within the hull, the handle 98 is grasped and pulled upwardly and around to bring the lip 91 upwardly from behind the hull wall to permit its being passed thcreover. At the same time the pins 95 and 96 have been carried rearwardly through the slotted portions 6 and have dropped into the notches around in which they may revolveas the door is swung open as shown by the dotted lines in Fig. 9. The depth of the notches is such that the pins 95 and 96 do not bottom therein until afterthe door has been raised somewhat on account of the fact that the pins are at a greater distance from the surface of the hull wall than is the door 90 itself. The notches 7 serve as means to prevent the rear part of the door, the lower part when the door is raised, from kicking forwardly when the door, is in the open position. Atransverse bar 99 is fixed between and carried by the plates 92 and 93 to serve as a stop against which the door 90 may rest when in the open position.

The hull 22 may be completelyrevolved. In many cases, particularly in washing with water, it is desirable to turn the hull around to bring its opening to the underside to dump the fluid quicklyover the edge.

lVhile I have here, shown and described my invention in the particular form as now best known to me, it is obvious that structural changes may be made without departing from the spirit of the invention, and I, therefore, do not desire to be limited to thatprecise form nor any more than may be required by the following claims.
